Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...

STUDY DESIGN Anthropomorphic phantoms were used to measure radiation exposure to the surgeon phantom's eye. Groups analyzed were: Group 1-no glasses (None); Group 2-leaded lenses without lead sides (WOLS); Group 3-leaded lenses with lead sides (WLS); and Group 4-sport wraparound leaded glasses (Sport). Glasses were 0.75 mm lead equivalent. OBJECTIVE To evaluate the efficacy of three types of ...

Background. Bedside radiological procedures pose a risk of radiation exposure to ICU staff. The perception of risk may increase the degree of caution among the health care staff and raise new barriers preventing patients from obtaining prompt care. Objective. The aim of this study was to estimate the annual cumulative radiation dose to individual ICU staff. Methods. In this prospective study, f...

OBJECTIVES To investigate and compare the knowledge of radiation dose and risk incurred in common radiology examinations among radiology residents, fellows, staff radiologists and technologists. METHODS A questionnaire containing 17 multiple choice questions was administered to all residents, technologists, fellows and staff radiologists of the department of medical imaging through the hospit...

An experiment was designed to determine the effect of radiation dosage on the synergism between radiation and estrogen in the production of mammary cancer. Female A x C rats had their left mammary chain exposed to graded doses of X-radiation while under anesthetic with urethan or sodium pentobarbital. The rats had previously been hysterectomized and exposed to estrogen by implantation with chol...

Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...

Physical mutagenesis is an effective mutational breeding method for improving various growth and floral characteristics of ornamental plants. The experiment was undertaken with objective to investigate the effect dosages gamma irradiation on survivability, Jasminum officinale plants raised by rooted cuttings. 60CO Gamma source at Horticultural Crop Research Developmental Institute, Gannoruwa us...

Microwave-induced in situ amorphization is a promising approach to circumvent stability and manufacturing issues associated with amorphous solid dispersions (ASD). Using amorphization, the crystalline state of drug converted into its form inside dosage form, e.g. compact, upon exposure microwave radiation. The study aimed investigate feasibility using glycerol as an enabling excipient compacts ...
